POLYMER COMPLEXES .29. NOVEL POLYMER COMPLEXES PREPARED FROM POLY(1-ACRYLAMIDO-2(2-PYRIDYL)ETHANE

Poly[1-acrylamido-2(2-pyridyl)ethane] homopolymer (PAEPH) and polymer complexes of 1-acrylamido-2 (2-pyridyl)ethane with a number of bi- and tetravalent transition metals have been prepared and characterized us ing spectral (H-1- and C-13-NMR, IR, UV-Vis) and thermal analysis, and magnetic measurements. The important bands in the IR spectra and the main H-1- and C-13-NMR signals are assigned and discussed in relation to molecular structure. Considerable interest has also been focused on the synthesis of the homopolymer and polymer complexes due to their p otential application. Tentative structures for the complexes are propo sed. Four types of Zr(TV) polymer complexes were prepared. In type [(A )+(C)] (1:1' metal:ligand) the chelate rings are five-membered, wherea s in type [(B)+(D)] (1:2) they are six-membered. The values of energy of activation of degradation of the compounds were determined from TG and DTA curves.
